## Summary

Great British Energy - Nuclear commissioned specialist commercial, project advisory and delivery support for its upcoming major procurements for the Gwyndod Small Modular Reactor programme. This is a re-procurement of its earlier Delivery Support Services contract. The work is business and management consultancy, including procurement advice, supporting the buyer’s procurement and project delivery activity. The buyer is Great British Energy - Nuclear, based in Warrington. The stated delivery locations span the United Kingdom and a range of international locations.

The procurement is complete and was awarded to Deloitte LLP on 28 August 2026. The awarded contract is valued at £6 million and runs from 29 September 2026 to 28 September 2028. The requirement was procured selectively as a call-off from a framework agreement. The procurement was valued at £6 million, with submissions due by 6 July 2026. The service is suitable for small and medium-sized enterprises. The published information does not set out specific evaluation criteria or divide the requirement into lots.

For suppliers considering similar future work with Great British Energy - Nuclear, this award shows demand for commercial, project advisory and delivery expertise tied to major nuclear programme procurements, specifically the Gwyndod small modular reactor programme. A credible competitor would need to demonstrate that it can provide specialist procurement and commercial advice alongside practical project delivery support for complex, high-profile procurement activity. The work was awarded through a framework call-off, so relevant framework access and the ability to compete under its terms would be important. Deloitte LLP, a large supplier, was selected; this indicates the requirement was delivered at substantial scale, though the award does not identify specific professional accreditations, staffing levels or experience thresholds.
